Answer: [tex]a=5000(1+0.055)^{15}[/tex]

Step-by-step explanation:

Given : George’s parents put $5,000 into an interest bearing account with a compound interest rate of 5.5%.

i.e. Principal amount : [tex]p=\$5,000[/tex]

Rate of interest : r=5.5%=0.055

George’s parents want to determine what the balance of his college fund account will be after 15 years. i.e. t= 15

Substitute all the values of p , r at t in the given formula [tex]a=p(1+r)^t[/tex], we get

[tex]a=5000(1+0.055)^{15}[/tex]

Hence, the correct substitution for the formula = [tex]a=5000(1+0.055)^{15}[/tex]
